Would This Be A Good Computer?

I want to know if this is a good processor:

AMD Athlon X2 4050e Brisbane 2.1GHZ Socket AM2 Processor

I am considering purchasing this computer which includes the processor above:

It seems like it is a nice computer for 200 bucks. It has a dual core processor and  supports PCI Express X16 graphics cards which is really convincing for such a cheap price. I just have one question.

What does HP Debranded mean? I need to know what that means before purchasing the computer. I am also aware that the computer has no operating system installed. Would I be able to load Windows XP on this system without RAID drivers since the motherboard already supports SATA?
